Tachyon Deck #773022 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 22/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: ocg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz and Fusion boss monsters (Galaxy-Eyes / Tachyon Dragon family) closing through Xyz Summons and Dragon-based Special Summons; Bystial Lubellion / Magnamhut beatdown and Light and Darkness Dragonlord Fusion pressure
• Turn 1 (going first): Open a Dragon starter, reach a 3000-ATK Xyz or Fusion boss, and protect it with Ash Blossom and Infinite Impermanence; the list is not legal, so this is structural only
• Turn 2 (going second): Use Droll and Ash Blossom hand traps to slow the opponent and then Special Summon a Dragon boss through the 13 hand-trap and negation cards
• Recovery: Recover through Schwarzschild Infinity Dragon, Galaxy-Eyes Afterglow Dragon and Tachyon Cloudragon, which each summon from hand or GY, and through Xyz material recursion
• After siding: No Side Deck is registered (side_count 0), so there is no post-side plan to evaluate

Why it scores here

The list has real engine access: the 12-copy Tachyon and Galaxy-Eyes core gives about a 72% chance of at least one core card in a 5-card opening hand, and 13 hand traps plus 18 negation-text cards give it strong end-board interaction and good going-second disruption. Those strengths are offset by poor structure: the archetype purity is 1.4% exact-name, 70 of 96 copies are off-archetype, and the Main Deck runs 26 distinct cards, so the engines do not reliably connect. The deck also has no recorded boards, no tournament link and no Side Deck, so combo ceiling and median output are text-only inferences. The list is Illegal: Seventh Tachyon and Ash Blossom are over their copy limits and Catapult Turtle is Forbidden. The score comes from the deck's structure and interaction read, not from Tachyon being a popular archetype, and card scores were not averaged. Because the list is Illegal, the final number is structural-only and capped low.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with a Combo secondary; no weight rebalancing applied. Structural ≈ 49, Going First ≈ 52, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12); illegal list cap (0). Final formula: Structural 49 (Midrange profile); uncapped 0.80*49 + 0.20*35 = 46.2, minus 12 banlist modifier = 34; Illegal cap applied, so the final score is 22 and the evaluation is structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong interaction density: 13 hand traps and 18 negation-text cards
• Accessible core engine: about a 72% chance of at least one core card in a 5-card opening hand
• Several 3000-ATK boss monsters with direct or piercing text

Weaknesses

• The list is Illegal: copy-limit violations and a Forbidden card
• Low archetype purity (1.4% exact name); 70 off-archetype copies weaken engine coherence
• No Side Deck registered, so no post-side plan can be assessed
• No combos or tournament data, so ceiling and median are text-only inferences

Critical choke points

• Engine starts depend on Seventh Tachyon and Ash Blossom, both over the copy limit
• Galaxy-Eyes and Tachyon boss lines depend on a small number of Extra Deck Xyz monsters

Recommended changes

Evidence & confidence

• Verified: Main Deck 56 and Extra Deck 15 are within size rules; Seventh Tachyon is over its limit (3 vs 1), Ash Blossom is over its limit (3 vs 2), Catapult Turtle is Forbidden; Exact-name archetype purity 1.4%, 70 off-archetype copies; Usage: 6 of 16 core cards present (37.5%)
• Inferred: About a 72% chance of at least one core card in a 5-card opening hand; 13 hand traps and 18 negation-text cards give strong interaction density; Going-second and end-board strength read from card text
• Provisional: Matchup fit and Meta Power (no tournament link or dated metagame sample); Side Deck adaptability (no Side Deck)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry: going-first, going-second and matchup rates are unknown No Side Deck: post-side plan and side adaptability cannot be assessed Meta Power stays provisional without a dated metagame sample
